Causes of homosexuality and other sexual orientations

Public opinion polls.

The Gallop poll periodically asks a statistically significant sampling of the American
public whether they believe that homosexuality is caused by nature or nurture. That is, whether it is:

a biological trait with which people are born, or

due to other factors, such as upbringing or environment, or

a combination of these factors, or

caused by other factors. 1

To those who accept the findings of peer-reviewed scientific studies, the correct answer has already been determined, at least for males. This is as a result of pedigree studies and by
studies of the sexual orientation of identical twins who were separated at birth and raised independently, as
described
elsewhere. The studies show that the tendency towards homosexuality is determined genetically. But that
this tendency may or may not be triggered during childhood into causing a homosexual orientation
later in life. Unfortunately, Gallup deleted "both" as an answer in recent polls.

However, many people in the U.S. reject a genetic cause over homosexual orientation. They accept the teaching of many religious groups that environmental factors such as child-raising styles used by parents or being sexually molested childhood are primary causes.

Asking the public about the causes of sexual orientation is like inquiring their belief
whether the universe was created by God or evolved due to natural processes. The answer only tells us of people's beliefs;
it has no impact on the actual causes of homosexuality.

It would seem that since the start of of the 21st century, the public's beliefs have been more or less stuck with approximately equal numbers believing in nature or nurture.
